GV80 3.5TT

[YEH]

Can't really even compare 0-60 times from different publications here, so wouldn't really rely on what Charlie got on a run while on a city road (plus, there have been days were it has been hot & muggy in Korea), but yeah, likely not going to be that much better.

But at the same time, seems like Genesis has tuned the standard 3.5TT for smoothness rather than performance.

The gear shifts in the 540i just seem more aggressive.

Would not at all be surprised if there's a significant diff. w/ the (presumably) GV80 Sport in terms of how the engine and trans are tuned/programmed.

The non-N-Line Sonata trims are geared as commuter sedans, but the N-Line should be markedly diff.

Hyundai/Genesis actual power is not to be compared to the big names. I have had no less than 3 Genesis in the past. The 4.6, a 5.0 rspec and the second gen 5.0. The car was nice but no way is there 420hp or should I say they mated it tamely or maybe the others under rate. Not sure what the reason is but there is definitely a major difference. The car was fast but not like my AMG 43 GLC which I was not expecting to be very fast with only 362hp compared to the 420 I had and similar weights.

GLC 43 3.0 4156lbs 362hp 383 torque. factory claimed 0-60 4.6, Car & Driver 4.5

2015 5.0 Gensis sedan 4200lbs 420hp 383 torque. 0-60 Car & Driver 5.9, actual video similar to the GV80 6.2?

Heck even the tamer non AMG version at 255hp does 5.4. 2020 Mercedes-Benz GLC300 Review: Is It a Good Small Luxury SUV?

Regardless, I am not buying a GV80 for speed, yes I like power but luxury, quiet and build quality is more important to me then 0-60 times. The 3.5TT is not underpowered IMHO just maybe not as fast as some of the competition but so what. Although I really like the power in the GLC 43 the ride sucks, harsh and rattles galore but dam this thing holds the road for a SUV and is really fast no matter when you hit the throttle. I have had the non AMG GLC as a loaner when servicing and the ride is so much better, probably would have been a better choice for me.

That "major difference" is because the AMG is turbocharged while the Genesis is naturally aspirated. Turbo engines have more usable torque in the lower rev range, which means you'll feel the thrust the moment you step on the pedal. The V8 has a smoother throttle response. Also, the G80 5.0 is a much heavier car than the GLC at 4500 pounds.

2015 5.0 Gensis sedan 4200lbs 0-60 Car & Driver 5.9

Those numbers are from C&D's test of the 3.8 naturally aspirated V6, which has only 311 horsepower. C&D got 4.9 seconds for the much heavier 4500 pound G80 Sport with the 3.3T V6.

Our opinions and expectations differ. Anything south of 7 seconds will get you to work on time. If I want fast, it won't be an SUV.
How are you ripped off? You know what is is going in so you make the choice, yes or no. If they told you 4 seconds and at best it is 10, then you got ripped off.

Like I said, if you're happy with 7 seconds, there's the 2.5T. There may be other factors someone chose the car such as the wife... lol

Think of it this way... why would someone waste thousands of dollars for the top audio system in a car when they just listen to the radio most of the time? It's for the times when they do listen to lossless audio that they want it to sound as clear as possible. I may use the car to go to and from work most of the time but the times I do want to stomp on it, I expect it to perform like the competition.

A full second if true is a big difference. Given the power and weight of the car, it should be in the mid 5's. If what Charlie got was accurate then there's something off with the car. A bad launch shouldn't be a full second off and most car reviewers would've done it multiple times and chose the best time or an average of the times. Just stomping the throttle should've got him close by a few 10ths of a second. A full second off from the competition is like a bad launch and misshifting which isn't really possible in an automatic. I'm going with there being something off with the car because if 6.5s is an accurate time, it's slower than a RAV4 Prime... lol

Same reason guy spend $2k for custom golf clubs and can't break 120. Same reason guys but a $2k Nikon lens and have no clue why the guy with a cheap camera can take better photos. and the list goes on.

Your money, your choice.

 

[YEH]

Well, the above accel test for the 3.5TT G80.

 

[Backslack]

Mystery solved. The GV80 is "slow" because, for whatever reason, these press models are using 92 RON (87-88 octane) regular fuel, as seen in this video (about half a second faster than Charlie's attempt, his launch really sucked ).

If you really want the full performance, you have to use the good stuff, rated at 95 RON (or 91 octane) and above. That will likely generate the earlier claimed 5.7s from 0-60.

 

[Midnightsun]

Nice, puts it in sub 6 for 0-60 easily. Plenty fast for a large luxury SUV. Pretty sure it wont be long before a chip kit comes out to bring it down to 5 for those who need the bragging right. Plenty fast for me in stock form from what I see on that last video.

Nice thing about Hyundai/Genesis is they can run off of regular fuel if one wants to and are not obligated to run 91. Nice to have the choice without worrying about warranty issues. I recall the difference on the 5.0 was a measly 7 hp. Cannot see this as making any noticeable diferrence in performance.

At least we have a good idea of what to expect and as time goes by there will be a bunch of others comparing with both fuels and 20" vs 22" tires, baseline 3.5 vs fully optioned with 3rd row seats.

 

[SuperKing]

Yeah, that sounds much better... lol More inline with the competition

Ha, was going to mention that being a possibility, but even w/ gas prices being what they are in Korea, why would Genesis cheapen out when giving out testers?

At least they should inform the reviewers of that fact so they can make note of it in their reviews.

I'm with you on this one. Makes no sense when you want folks to see you at your best. That does make more sense. Went to LR yesterday and it was strange. I asked for the sales person I had spoken to months ago. He's one of the owners family members. I waited for nearly an hour and he never showed. When I went to the front desk (manned by a much older man who is also part of the family who owns them) he just talked and told me how they hold the line on their prices and how much extra they give the customers etc... Then he excused himself and went back to his office. I then went to his glassed in office and thanks him for his time and told him I just wanted to test drive the cars. He said that I should have told him that up front and told me he would get someone to take me out. I thanked him again and told him it was way too late. There are other dealers around.

That wasn't an experience I expected. They have lost my business to say the least.

It's an odd decision for sure. Makes me question if the new G80 press models are using regular as well. Most reviewers have been able to hit 5.5 seconds regularly with them, though it is a few hundred pounds lighter than the GV80. If that number is from regular fuel, premium ought to put it in the flat to sub 5-second range, which is on par with the Germans.

If I had to guess, I would assume regular was used because the core audience for the GV80 in Korea care little for performance. Curious what the US spec models will say to put in the tank.

 

[ctsooner]

I got to Costco and will use their premium if I get one. No question about it since they are tuned to use that high an octane.

 

[SuperKing]

I'm curious how much power it loses on regular fuel? My MR2 Turbo did 6.3s stock and it took an extra 45 horses for me to get it down to 5.5S but I really doubt the GV80 would lose that much power on regular fuel. Maybe 15-20 horses max.

I don't think we're going to shave off half a second going to premium fuel.

EDIT: added word "think"

Only way to find out is to test it. Has anyone attempted a 0-60 run with their G80 Sport on regular? It's not the same engine, but it would give us a good idea of how Genesis tune their engines for different fuel types.

Here's a Korean article on the G80 Sport, where they claim the 0-60 time is 6 seconds based on their tests:

Yet, western sites like C&D and Motor Trend claim times of 4.9-5.2 seconds. There is a substantial difference in the numbers.

 

[EdP]

I don't we're going to shave off half a second going to premium fuel.

Depending on how much you drive, it could be $300 to $400 a year for that half second. Worth it to you?

Not for me, but if I was out cattin' around on a regular basis, running light to light races for fun - it could be. You never know when you'll encounter your same car in a street light race.. after all, he could be burning regular!

 

[Midnightsun]

As I mentioned before the V8 had the figures listed from the factory. Premium was 420 and regular was 412. 7 hp won't even give you 1/10 of a second. Premium fuel vs regular will normally produce about 2% if the engine is designed for it. That being said it probably equates to 6hp in the GV80 3.5TT. Guys, this is not going to make the least difference IMHO. Temperature, humidity and the weight of the driver will have more effect than type of gas. Depending on options the weight could vary by up to 400lbs. 22" wheels, weight of all the goodies and 3rd row seats.

Peak power has little to do with off-the-line acceleration, what matters is how much of it is usable in the lower RPMs, and in that regard torque is more important- especially so on turbo engines where all the torque comes at 1500 RPM or so. Performance on regular fuel is dwindled compared to premium because the variable valve timing has to be readjusted by the computer to prevent engine knock. On high compression and boosted engines like the 3.3T, that tends to slow down the ignition timing, making the engine respond more slowly.

This article sums it up pretty nicely:

A smart engine that desires high octane fuel for optimum performance will retard the ignition timing to prevent knock when lower octane fuel is used, and advance the timing once it sees more desirable fuel again. An unintelligent engine which desires high octane fuel likely won’t be able to adjust the timing accordingly, and thus will be able to run on both low or high octane fuel rather equally.

Engineering Explained: High vs Low Octane Petrol

With fuel prices staying fairly low recently, is it worth it to shell out extra cash for some premium petrol? And what do those numbers mean anyway?

www.carthrottle.com

The 5.0 Tau was tuned for smooth cruising and is not a high performance engine like say the V8 in the Lexus GS-F, and so putting in regular or premium doesn't seriously affect the valve timing. I also doubt you'll feel the difference in acceleration off the line anyway since the torque doesn't kick in instantly like a turbo engine. And if I'm being honest, nobody would "feel" half a second of difference from 0-60 unless they had a timer. But not feeling it doesn't mean it's not there.

Other than that, I agree that there are a million factors that go into 0-60 times, which is why Charlie and that other guy had a whole half second of difference despite using the same car with the same equipment and the same tires and the same regular fuel. The cars can't come here soon enough.
